In the model with utilities
Wi = ci + α ln(xi)
where individuals are endowed with ability levels wp < wm < wR and form fractions πp, πm, πr with πm > πp, πr such that the median person is in group m.
-  Find the median voter eqm.
-  Now consider a situation where wp falls. What changes at eqm?
-  What if wm rises?
